Definitions

  • the invention concerns a lid for containers comprising an edge region for—preferably sealing and permanent—connection to a container body comprising a body wall and a bottom.
  • a container body comprising a body wall and a bottom.
  • the lids which serve for closure purposes can for that purpose have tear-open regions provided with a gripping tab (tab), for non-reversibly opening an outlet opening, as is known in particular from drinks cans.
  • the invention therefore also preferably relates to sheet metal lids for closing beverage can bodies.
  • the object of the invention is to further develop a lid for a container body, such that in manufacture of the lid means are provided thereon which make it possible to fit one or more additional elements to the lid in such a way that they can be linearly moved relative to the lid in a direction in a given relationship with the axis of the lid.
  • additional elements themselves are not subject-matter of the invention.
  • the lid according to the invention has at least one or more guide elements in the substantially flat region (as a central planar region, panel or lid surface) which is surrounded by the edge region which serves for connection to the container body.
  • the guide elements are in the form of pin-like or post-like guide elements and oriented substantially with their axis approximately parallel to the axis of the lid, which extends perpendicularly with respect to the lid surface.
  • a corresponding device can be reliably guidedly moved on that guide element or those guide elements, as a sealing closure element, linearly relative to the lid surface and approximately in the direction of the axis (lid axis).
  • a guide element as a protruding element is of such a height and configuration that it is suitable for guidance purposes, that is to say it allows a stroke movement or a displacement directed away from the surface region, in the heightwise direction.
  • the at least one guide element is arranged outside the opening.
  • the guide elements can extend from the top side of the lid and/or from the bottom side of the lid, preferably inwardly relative to the interior of the container body.
  • the edge region (or also edge) extends around the central surface region. It is suitable for being fixed to the container body by a folded seam connection or bead connection. That body can be made in one piece, that is to say with a bottom, produced directly without a fold seam, on the body wall, which is often also referred to as the ‘body’. The body itself however is not subject-matter of the lid in accordance with the independent claims.
  • the sealing and permanent connection is afforded by the folded seam which is produced in an operation of flanging or folding the edge region of the lid on to the rim of the container body which matches it in associated relationship, that is to say the upper end of the body as the body edge.
  • the two edges are matched to each other in such a way that the folded seam provides the sealed and permanent connection of the lid for closing the container body.
  • a closure function and an opening function which then possibly take place, by way of re-closure of an additional element, can be effected in such a way as to be controlled and guided by way of the guide elements associated with the sheet metal material of the lid.
  • the guide element it is to be stated that they do not or cannot lie in the free opening, they are provided outside that relatively large opening.
  • the at least one pin-like or post-like guide element is provided in that intermediate region. It protrudes towards one side or the other, preferably towards the interior of the container body and thus towards that side which defines the edge region of the lid in such a way that it can be connected to the body edge by being placed thereon.
  • the edge region it is in most cases a channel-like curvature region.
  • the man skilled in the art can recognise from that form of the curvature region, which side of the lid is directed towards the container and which side faces outwardly.
  • the guide element is of a thickness which remains substantially the same. That thickness extends over the length of the guide element.
  • a preferred height is above 5 mm.
  • the cross-section of the at least one guide element can remain the same along that height.
  • the arrangement of the at least one guide element in the proximity of the edge of the opening is to be interpreted as meaning that it is adjacent to the opening.
  • the guide element is thus markedly closer to the edge of the opening, than the connection edge region.
  • the guide elements are displaced substantially further inwardly than outwardly, in the intermediate region. They are at the edge of the ‘free opening’.
  • guide elements are fitted, for example two guide elements which are disposed in mutually opposite relationship and which extend towards the same side, it is possible to achieve a particularly accurate parallel guidance effect.
  • the guided element for secure re-closure, cannot then tip, but is kept substantially parallel in its position and is reliably guided in a direction perpendicularly to the plane of the central surface region, by a removal movement and a fitting movement.
  • the at least one guide element can be made from sheet metal or plastic material.
  • the lid can be manufactured jointly with the guide elements. That joint manufacture in the form of a unit is preferably implemented using injection casting technology. That injection casting procedure is a representative of pressure forming with which the guide elements can be formed in position.
  • a continuous plastic material layer which carries the one or more guide elements, or is formed in one piece with those guide elements respectively.
  • the connection of the plastic material layer to the lid surface provides the hold for the guide elements on the metallic lid material.
  • That hold can be implemented by a peripherally extending strip at the edge of the opening. In that respect it can be in the form of a strip at one side or two sides, in which case the arrangement can provide a U-shaped profile. Fitting the profiled layer provides for reliable positioning and orientation of the guide elements. The layer and therewith the guide elements can then no longer be separated from the lid, without involving destruction. It will be appreciated that a plastic material layer produced by injection molding or pressure shaping is formed in one piece with guide elements.
  • the opening is of a relatively large configuration.
  • the embracing configuration at the edge and from the interior therefore involves a comparatively large radius, in the case of a circular hole.
  • the integral mounting can also be paraphrased otherwise as ‘lockingly involving intimate joining of the materials concerned’.
  • this at least one guide element is suitable for permitting guided displacement in the heightwise direction, which is not only a statement of use but also a way of paraphrasing the technical function involved and thus a functional definition of such structurally designed guide elements which allow such displacement in the heightwise direction, and such ‘holding elements’ which precisely do not allow that displacement in relation to the sheet metal of the lid.
  • DE-U 202 19 794 (Blechwarenfabrik Limburg) illustrates a stackable container with an edge region 5 for sealing and permanent connection to the container body consisting of the body 2 and the bottom 4 (the references are taken from that publication).
  • That design has a substantially planar central region (reference 3 therein) in which there is an opening delimited by an edge, for introducing or removing the filling material (the opening is identified by reference 17 therein).
  • Arranged in the region between the edge and the opening is at least one element with which a gripping means (reference 18 therein and FIG. 3) is held to the lid surface. Those gripping elements are only visible there in FIG.
  • FIG. 1 shows a view in axial section of a container, closed with a lid which is produced in accordance with an example of the invention
  • FIG. 2 shows a plan view on a larger scale of the lid of FIG. 1 , with a free opening in the panel,
  • FIG. 3 shows a view in cross-section of the lid of FIG. 2 .
  • FIG. 4 a shows a plan view of a portion of a lid surface with a filling and/or removal opening, prior to shaping of the guide elements
  • FIG. 4 b shows a perspective view of the portion of the lid of FIG. 4 a after shaping of the guide elements
  • FIGS. 5 a , 5 b and 5 c show perspective views of three guide elements with various examples of their cross-sectional configuration
  • FIG. 6 shows a cross-section of portions of further embodiments of a lid with guide elements.
  • FIG. 1 shows a typical container body 4 (which can be referred to just as the ‘body’), as is usual for example made of sheet metal by deep drawing or stretching for beverages. It includes a cylindrical body wall 5 with a longitudinal axis 9 and a bottom 6 connected in one piece to the body wall.
  • a lid which is manufactured or designed in accordance with a number of examples of the invention is connected to the container body 4 by a sealing permanent seam which is formed over the edge of the body and the edge of the cover 2 , being in the form of a folded join 2 a .
  • a damping bead 2 b (anti-peaking bead) is disposed between the folded join 2 a and the panel 3 , as a surface region.
  • the lid 1 has a ‘lid surface’ (in the form of a panel or central planar region 3 ) which is substantially flat and which is connected by the lid edge 2 by way of a damping or anti-peaking bead 2 b (to the chuck wall).
  • the lid panel has three guide elements 7 ′, 7 ′′ and 8 .
  • the two guide elements 7 extend parallel upwardly while the guide element 8 extends from the panel 3 downwardly (or inwardly of the container).
  • All three guide elements are arranged parallel to each other and parallel to the axis 9 of the lid 1 . They are in the form of pillars, posts or pins. They can extend over a length of between 5 mm and 15 mm.
  • One or two of those guide elements are sufficient, for example the two pins 7 ′, 7 ′′ also being directed inwardly.
  • the cross-section of the guide elements is approximately circularly round.
  • the cross-section may also be quite different.
  • the shape of the cross-section depends on the purpose of use, that is to say the nature of the device which is to be guided at the guide elements, that device itself not being subject-matter of the invention.
  • the at least one guide element can also be oriented at less than 90° with respect to the plane of the lid surface, for example between 75° and below 90°, as symbolically shown by the angle ⁇ in FIG. 3 .
  • the guide element 8 or also the guide element 7 ′′ is oriented at an angle of less than 90°, corresponding to that angular orientation. That applies, for a parallel orientation of the guide elements 7 ′, 7 ′′, also for the guide element 7 ′ which has hitherto not been mentioned.
  • the guide elements represent respective longitudinal axes which then no longer extend parallel, with respect to the longitudinal axis 9 .
  • the longitudinal axis 9 has hitherto been referred to as the container axis, but is also a congruent longitudinal axis with respect to the lid, as shown in FIG. 2 at the centre point of the lid panel 3 .
  • FIGS. 4 a and 4 b by reference to the example of a lid of sheet metal, show the operation of shaping the guide elements by bending the sheet metal of the lid.
  • the opening 16 in the lid panel 15 the opening being defined by an opening edge 17
  • two mutually oppositely disposed sheet metal flaps 18 ′, 18 ′′ are left.
  • cuts are made thereinto at both sides at 19 ′, 19 ′′, leaving a bridge region 20 .
  • the flaps are bent away at the bridge region 20 through about 90° relative to the lid surface (bend location 20 a ) and rolled in to form a respective cylinder indicated at 18 a.
  • the guide elements can also be produced by deep drawing or the like directly from the lid material.
  • the guide elements can be applied to the material of the lid surface by using pressure and increased temperature, together with a continuous plastic material layer, by ‘pressure shaping’ thereon.
  • the lid and the guide elements can also be shaped as a unit from a non-metallic material.
  • FIG. 6 in section and as a portion from the metallic lid panel 40 —shows a continuous plastic material layer 43 which is applied along the edge 42 of the opening 41 in the panel 40 in production of the lid by pressure shaping, wherein the plastic material layer 43 in the illustrated example also at least partially embraces the opening edge 42 (at 43 ) and, fitted in one piece, has the at least one and preferably both guide elements 43 b ′, 43 b′′.
  • the entire lid surface with the guide elements can also be formed from plastic material and can be fixedly joined by pressure shaping to a ring portion of metal, which has the lid edge, in the above-described manner.
  • the lid can be varied easily and with a high level of precision without involving major complication or expenditure, for any corresponding purpose of use. It is preferred for the field of closing drinks cans, which defines its panel, its size (under 60 mm in diameter) and its edge flange 2 which is suitable for the folded seam connection. Likewise the thin sheet metal thickness.
